The catch here is that you need a creature to die in order to make use of the card, but thats not too hard to arrange
It also nullifies your opponent's graveyard - pretty backbreaking for strategies like 'Dredge' that rely on the 'yard - and allows you to grab your opponent's best threat from the void and play it free of charge (Okay, at the cost of its own life, but it's a lowly two-drop, so who cares?) Paired with targeted discard cards like the popular Thoughtseize, Dauthi Voidwalker has the potential to be super scary
Chain Lightning is a staple of Legacy burn decks

$150 isnt out of the question, especially if Slivers are confirmed at some point, but the ship has probably already sailed on making any reasonable profits here
